描述 Description

Si8285BD-IS?are isolated, high current gate drivers with integrated system safety and feedback functions, ideal for driving IGBTs used in a wide variety of inverter and motor control applications. Si8285BD-IS? devices support up to to 5?kVRMS withstand voltage per 9, provide feedback to the controller about the driver side power state and fault state and recover the device from fault through an active-low reset pin. On the output side, the Si8285BD-IS?provides separate pull-up and pull-down pins for the gate. A dedicated DSAT pin detects the desaturation condition and immediately shuts down the driver in a controlled manner. A Miller clamp is also integrated in to facilitate a strong turn-off of the power switch. Orderable options in the Si8285BD-IS?family include an integrated, isolated dc-dc controller. This provides a simple method for providing the isolated power rail necessary for the isolated driver and significantly simplifies layout. Si8286 devices are packaged in a configuration common to many optocoupler based IGBT drivers.
